The LED light source system comprises a shell, wherein the inner left side of the shell is provided with an LED chip, a light gathering cover and a radiating fin; the LED chip, the light gathering cover and the radiating fin are all positioned on the upper part of the shell; the radiating fin is arranged on the shell; both the LED chip and the light gathering cover are arranged at the right end of the radiating fin; the LED chip is positioned on the focal point of the light gathering cover; a driving circuit for driving the LED chip is arranged inside the shell; the driving circuit is positioned on the lower part of the shell; an optical fiber bundle socket is arranged on the inner right side of the shell; a reflective light cone is arranged inside the optical fiber bundle socket; the reflective light cone and the LED chip are positioned on the same axis; and an optical fiber bundle is spliced into the right end of the optical fiber bundle socket. The LED light source system has a compact structure, a reasonable design and high coupling efficiency, and the problems of low coupling efficiency, high energy loss and difficulty in increasing brightness existing in the prior art can be solved effectively; and meanwhile, the LED light source system has the characteristics of small size, low cost, high brightness, energy saving and environmental friendliness.

Description

technical field [0001] The invention relates to a light source system, in particular to an LED light source system for high-efficiency optical fiber bundles. Background technique [0002] At present, optical fiber bundles (referred to as optical fiber bundles) have been widely used in many fields such as decoration, lighting, and medical treatment. Most of the light source systems for optical fiber bundles use direct irradiation, that is, the light emitted by the light source directly irradiates the end face of the optical fiber bundle. Only part of the light energy is coupled into the fiber bundle, because the divergence angle of the general light source is large, and the diameter of the fiber bundle is small, resulting in low coupling efficiency and large energy loss, and is limited by the brightness of the light source and coupling efficiency, it is necessary to increase the output brightness of the fiber bundle more difficult.
